ON Wednesday night, as a fierce northeaster bore down on the weather-beaten Rockaways, the relief groups with a noticeable presence on the battered Queens peninsula were these: the National Guard, the Federal Emergency Management Agency, the Police and Sanitation Departments — and Occupy Sandy, a do-it-yourself outfit recently established by Occupy Wall Street.

This stretch of the coast remained apocalyptic, with buildings burned like Dresden and ragged figures shuffling past the trash heaps. There was still no power, and parking lots were awash with ruined cars. On Wednesday morning, as the winds picked up and FEMA closed its office “due to weather,” an enclave of Occupiers was huddled in a storefront amid the devastation, handing out supplies and trying to make sure that those bombarded by last month’s storm stayed safe and warm and dry this time.

“Candles?” asked a dull-eyed woman arriving at the door.

“I’m sorry, but we’re out,” said Sofia Gallisa, a field coordinator who had been there for a week. Ms. Gallisa escorted the woman in, and someone gave her batteries for her flashlight. As she walked away, word arrived that a firehouse nearby was closing for the night; the firefighters there were hurrying their rigs to higher ground.

“It’s crazy,” Ms. Gallisa later said of the official response. “For a long time, we were the only people out here doing relief work.”
